This is a'H in Figure III; it must be part of any equilibrium. Low-risk customers would, of all contracts on EL, most prefer contract d which, like aH, provides complete insurance. However, i3 offers more con- sumption in each state than aH, and high-risk types will prefer it to aH. If f and aH are marketed, both high- and low-risk types will purchase A. The nature of imperfect information in this model is that insurance companies are unable to distinguish among their customers. All who demand ,3 must be sold A. Profits will be negative; (aHfi) is not an equilibrium set of contracts.
